There's a girl I'm advancing on who I've known her for over a year now and we've been on friendly terms (I wasn't interested then hence why). She's in two of my classes so I see her pretty often. The past month, I started playfully teasing her. We laugh at each other a lot and she even got her friend to give her my Snapchat. The only issue is, I'm afraid we're teasing each other too much since that's mainly what we do when we see each other. Sure, we have conversations then and there but we mostly just tease, joke around and laugh. I want to make a move real soon and ask her out but I feel like I might be ruining my chance if I continue teasing her the same way I am now.

How shall I proceed?
